Taking vitamin D supplements has been found to aid weight loss in obese and overweight people, Italian researchers have found.
Scientists at the University of Milan estimate that in northern Italy, severe vitamin D deficiency ranges from six per cent in overweight people to 30 to 40 per cent in the morbidly obese.
Almost all obese subjects did not have a vitamin D level in the optimal range.
For the study they recruited 400 obese or overweight adults who were split into three groups - those who took no supplements, those who took 25,000 vitamin D units a month, and those who took 100,000.
All participants were put on the same balanced, low-calorie diet.
After six months, only those who took 100,000 units a month achieved optimal vitamin D status.
However, a significantly greater weight decrease and reduction in waist circumference was observed in both groups that took the supplements.
